The Mullvad team has been using Qubes in its day-to-day operations since early 2015. It allows us to compartmentalize and isolate activities with different security requirements, such as server administration, software development, and password management.

For us, Qubes is an important tool in our efforts to make censorship and mass surveillance ineffective. If you're concerned with the security of your computer, then you potentially have a lot to gain from using Qubes.
